Hi
In my home music studio one of devices I use
is signal processor (multieffect) Lexicon MPX100
It is fantastic machine however there is one problem
- signal level on output is very low
There is input knob and output knob
Input one I can't turn more - clip.
Output is on max and final signal still very low
even turned up on mixer to maximum.
It makes me a lot of mixing problems.
Comparing to signals from other instruments/processors
on the mixer it is very low
I was just wondering if I could (with your help)
make some simply modification on PCB
I have soldering/desoldering experience
but no theoretical knowledge
is it possible to boost signal by simply replacing some of components
like resistors? I don't think I will be able to replace whole opamp
or output potentiometer itself (I think it is R97) but maybe R88/98?
or R102/104 (I'm simply guessing)
I will appreciate any tips and help
schematics and pic of unit attached
